made it a law: From this history, and from Diodorus Siculus - lib. i. we learn that the land of Egypt was divided into three parts: one belonged to the Priests - Gen 47:22, and Gen 47:26, a second was the king's - which appears to have been the land of Rameses, or Goshen, Gen 47:11, the remainder was the subjects'. Now Joseph, having purchased the land of the people - Gen 47:19, and Gen 47:20, restored it, on the condition of their paying a fifth part of the produce to the king, beyond which he appears to have made no demand.
except: Gen 47:22, Eze 7:24
priests: or, princes, Gen 47:22
